Obsolete — sourcing reality for this MEMS oscillator
The DSC6101HI1A-025.0000 is listed as Obsolete by Microchip Technology. Any substitute will require a board-level evaluation — the package, supply voltage, and output type must match the existing footprint.
What the key ratings mean for fit
25 MHz CMOS output at 3 mA typical draw — the low current suits battery-powered or thermally constrained designs where a standard crystal oscillator would pull 10-15 mA.
Where this MEMS XO fits in a design
The 25 MHz frequency is a common reference for CAN FD, Ethernet PHYs, and MCU clock inputs in automotive body controllers and infotainment modules — the CMOS output drives a single load directly without an external buffer.
